Summary

Enterprise software architect and senior backend engineer with 17+ years of experience designing and delivering scalable cloud-native systems for banking, payments, trade finance and enterprise platforms. I design and deliver event-driven microservices end-to-end from architecture and Java/Spring Boot implementation through to Kubernetes, GitOps and observability on AWS, GCP and Azure.

Strongest where backend engineering meets infrastructure: reducing latency and cloud cost, hardening reliability, and replacing legacy ETL/monolithic systems with Kafka/Debezium CDC pipelines, Temporal workflows and Istio-based service meshes. Equally comfortable as in-house senior engineer/architect or as an independent freelance contractor.

Recently focused on enterprise AI enablement, intelligent automation, AI-assisted development workflows, and scalable platform architectures for integrating modern AI capabilities into enterprise ecosystems. Experienced in collaborating with cross-functional stakeholders, translating business requirements into scalable technical solutions, and aligning platform architecture with enterprise governance and strategic objectives.
